General notes
Method of operation The vehicle is equipped with a high-voltage bat-
tery for driving. The high-voltage battery stores
the energy needed to operate the electric motor
and releases it again.
The electric motor uses energy that has been
stored in the high-voltage battery when pulling
away, accelerating and during the journey.
In overrun mode, kinetic energy is converted by
means of energy recuperation into electrical
energy and stored in the high-voltage battery.
Information on overrun mode ( Y
page 253).
The high-voltage battery can be charged as fol-
lows: R
through energy recuperation while the vehicle
is in motion R
through the combustion engine while driving
in CHARGE operating mode ( Y
page 243)R
with the relevant charging cable at an electri-
cal outlet while the vehicle is stationary R
at a wallbox while the vehicle is stationary R
at a charging station while the vehicle is sta-
tionary
The high-voltage battery can be charged in a
nominal voltage range from 100 V to 240 V.
You can view the condition of charge of the high-
voltage battery in the multifunction display. You
can find information in "PLUG-IN HYBRID oper-
ation", section "Menus and submenus" under
"Energy flow display" ( Y
page 245).Charging the high-voltage battery (PLUG-IN HYBRID vehicles) 181
Driving and parking Z

High and low outside temperatures Low outside temperatures
At very low outside temperatures the maximum
power output of the high-voltage battery may be
reduced. The high-voltage battery is then no
longer able to provide the normal electrical
power output.
High outside temperatures
To prevent damage to the high-voltage battery
due to very high outside temperatures, the max-
imum power output of the high-voltage battery
is reduced by the vehicle.
Energy consumption and electrical
range The maximum electrical range is generally
reduced by: R
high and low outside temperatures R
operating the climate control system R
switching on consumers
The battery's physical characteristics are such
that leaving the vehicle parked for long periods
at low outdoor temperatures without charging it
can lead to: R
a reduction in battery performance R
longer charge times
Notes on battery care Avoid storing or transporting the vehicle at
excessively high or low temperatures over a long
period.
If you park the vehicle and leave it stationary for
long periods: R
check the condition of charge of the high-
voltage battery more often R
connect the vehicle to a power supply
This prevents self-discharge and damage to the
high-voltage battery.
Terms of use
Please note the information on exceptions and
limitations in warranty documentation and in
the Maintenance Booklet. Handling the charging cable and charg-
ing cable controls Do not leave the charging cable controls
( Y
page 183) hanging loose from an electrical
outlet. Otherwise, this could result in a poor
contact with the electrical outlet and malfunc-
tions when charging the vehicle.
To ensure that the brackets within the charging
cable controls are not subjected to incorrect
loads, observe the following: R
Never lift or carry the controls by the charging
cable connector or the mains plug. R
To transport the charging cable, the charging
cable can be: -
wrapped around the controls or -
secured to the housing of the controls
Heat generated by the charging cable
and charging cable connector Pay attention to the "Important safety notes"
( Y
page 180).
During the charging process, the charging cable
and charging cable connector may heat up.
The charging cable and the charging cable con-
nector will only heat up within the permissible
limiting values, provided that: R
the power supply and the charging cable are
not damaged R
the instructions for handling the charging
cable and controls on the charging cable are
observed
If the charging cable or charging cable connec-
tor become too hot, have the mains power sup-
ply checked.
Protection device against overvoltage
! Overvoltage in the mains supply may dam-
age the vehicle. For this reason, the vehicle is
equipped with a protection device against
overvoltage in the mains supply. This device
may be triggered during severe thunder-
storms, for example, and may lead to the buil-
ding's fuse being tripped and an interruption
in the power supply. These functions protect
the vehicle. After the building fuse is switched
on again, the charging process resumes auto-
matically. Following an interruption in the
power supply or tripping of the building's fuse,
it may take up to 10 minutes for charging to
resume automatically.182

G WARNING
If the charge current draw via a mains socket
is too high during the charging process, the
external electrical system may overheat.
There is a risk of fire.
Before beginning the charging process, check
the maximum permissible charge current
locally. Consult a qualified expert to do so
where necessary.
If necessary, adjust your vehicle's settings.
! An excessive charge current can blow a fuse
or lead to overheating of the external power
supply. Check whether the external power
supply is compatible with the set charge cur-
rent. If necessary, lower the set charge cur-
rent or use another power socket.
Before starting the charging process at a power
socket, check the maximum permissible charge
current for the relevant power socket or the
building.
You can set the maximum permissible charge
current: R
on the controls of the charging cable R
in the on-board computer menu
( Y
page 272).
The lower value of the two charge current set-
tings – on the charge cable controls and in the
on-board computer – determines the maximum
charge current. If you cannot set the precise
maximum permitted charge current, select the
next lowest available value.
Only set the maximum permitted charge current
in the on-board computer menu if: R
it is not possible to set the charge current on
the charging cable R
the precise maximum permitted charge cur-
rent can only be set via the on-board com-
puter
